From a397ba829d7f8aff4c90af3704573a28ccd61a59 Mon Sep 17 00:00:00 2001 From: Marcelo Cerri Date: Wed, 28 Sep 2016 13:42:09 -0300 Subject: [PATCH] crypto: ghash-generic - move common definitions to a new header file Move common values and types used by ghash-generic to a new header file so drivers can directly use ghash-generic as a fallback implementation.
